BU4848FVE-TR

Supervisors Overview

The BU4848FVE-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply voltages. It features an open-drain output type and operates within a reset active voltage range of 0.95 V to 10 V. The typical under-voltage detection voltage is 4.8 V with a precision of ±1%. The circuit current is specified at 0.60 μA when on (at VS=4.8V) and 0.85 μA when off. Hysteresis voltage is defined as VS x 0.05. It supports a maximum operating temperature of 125°C and utilizes a VSOF5 package.

Supervisors Feature Summary

• CMOS technology ensures low power consumption suitable for battery-operated systems
• Open-drain output configuration allows flexible logic level interfacing
• Wide reset active voltage range accommodates various system voltage levels

Supervisors Applications

• Portable electronic devices requiring voltage supervision
• Battery-powered equipment needing under-voltage protection
• General-purpose embedded systems with single-channel monitoring needs

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as this part may be obsolete. Ensure the VSOF5 package matches your PCB footprint requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 4.8 V threshold is required without manual reset or watchdog capabilities. Consider the open-drain output compatibility with your microcontroller input voltage levels. Evaluate the low standby current against system power budget constraints and verify thermal performance within the -40°C to 125°C operating range.

Supervisors Part Context

This device belongs to ROHM's standard voltage detector family, providing simple supervisory functions. It lacks advanced features like adjustable thresholds or auto-reset timers found in other series members. The VSOF5 package offers a compact surface-mount solution for space-constrained designs requiring reliable voltage monitoring.

Supervisors Replacement Considerations

The BD5248G-1 is listed as a similar specification replacement option. Verify package compatibility between VSOF5 and SSOP5 forms. Check if the hysteresis definition and current consumption parameters meet your specific design requirements before substituting.
